In MT8195 SOF design, both DSP and audio driver would access audio registers. Before DSP accesses audio registers, audio power and clock should be enabled. DSP will hang up if DSP access audio register but audio power and clock are disabled. Therefore, we add audio pm runtime active checking before accessing audio registers in SOF BE's callback hw_params function to avoid this situation.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
